Adding more to the design

I want to keep the whole of cubicgarden.com quite consistent in design, even though there are many different applications and services running under the site banner. The way I do this is by using the same external css for all the sections. But recently my designer side has been tweaking and fiddling with the css to see what else i can introduce to the site. So please dont be alarmed if the site design changes from day to day. Its just me fiddling.
